Okay, my LFB and banked flip() -functions work. The problem is that
while linear flip is rather fast, doing that in banked mode is
really, REALLY slow, probably because code has to switch into
real mode 6 times during the whole flip-operation.

The question is, is there a way to change video pages in 
protected mode (VESA 1.2), or some other way to do it _fast_?
